Minimum weight design of a rectangular panel subject to a flutter speed constraint
The thickness distribution for a simply supported rectangular panel is determined for minimum panel weight and a specified aeroelastic eigenvalue. Finite difference equations are used for derivatives with respect to the spanwise variable so that the partial differential constraint equations are appr...

| Summary: | The thickness distribution for a simply supported rectangular panel is determined for minimum panel weight and a specified aeroelastic eigenvalue. Finite difference equations are used for derivatives with respect to the spanwise variable so that the partial differential constraint equations are approximated by sets of ordinary differential equations. Numerical solutions are obtained for the resulting optimal control problem using a gradient projection algorithm. |
